Back strenghthening maching

ABSTRACT

An improved back strengthening machine  5  having a rolling cushion assembly unit  1  contoured to firmly contact all back surfaces and strengthen all dorsal muscle groups. In addition, the back strengthening machine  5  comprises: a rolling cushion assembly unit  1,  weight resistance assembly unit  2,  base assembly unit  3  and a handlebar assembly unit  4.  While using this machine, a user will stand onto base of base assembly unit  3,  hold onto hand grips adhered to handlebar assembly unit  4,  and then press onto the rolling cushion adhered to rolling cushion assembly unit  1,  while aligning the elevated convex cushion shape onto the spinal location. Next, the user will use knee flexion to maintain the spinning cushion adhered to rolling cushion assembly unit  1,  to spin freely up and down the user&#39;s back structures.

BACKGROUND OF THE INVENTION

1. Field of Invention

This invention relates to back strengthening machines, specifically tosuch which use weight resistance during operation.

2. Prior Art

A consumer purchases back strengthening equipment in order to exerciseand strengthen all of their back muscles. Ultimately, these devicesshould be capable of strengthening all dorsal muscle groups.

Indeed, several designs of back strengthening machines were invented.However, these former designs only partially strengthen dorsalstructures. This is clearly shown in U.S. Pat. No. 5,618,250 to Butz(1997) and U.S. patent D439, 938 S to Batca (2001) wherein, bothmachines lack a cushion that makes total contact with all backstructures.

These cushions fail to rotate along the entire spinal column or all backstructures. Ultimately, these devices only slightly activate the partialstrengthening of back muscles.

Thus a later back strengthening machine depicts similar lacking designfeatures-in example U.S. Pat. No. 6,387,024 B1 to Monti (2002). Thisback strengthening apparatus clearly fails to make contact with alldorsal muscle groups. The absurd shape of its back strengthening rollingcushions is two lateral components, which lack a continuous contactsurface for all dorsal structures. Indeed, they fall short of anysurface contact for the spinal column. Nor do these lateral cushionsroll along the entire back thereby ignoring the lumbar region and lowerback structures.

Conclusively, heretofore-back strengthening machines render subsequentusers to succumb nonetheless, into an unbalanced strengthening of backmuscles. Therefore, the need still exists for a back strengtheningmachine that can apply equal weight resistance to all dorsal structures.

3. Objects and Advantages

Accordingly, besides the advanced structural aspects and optimum dorsalexercise technique of the back strengthening machine in my above patent,several objects and advantages of the present invention are:

-   -   (a) to provide a back strengthening machine which enables the        amount of weight resistance to be used easily adjustable;    -   (b) to provide a back strengthening machine whose rolling        cushion contour will adequately make firm contact with all back        structures;    -   (c) to provide a back strengthening machine whose embodied        weight resistance will sufficiently exercise all dorsal muscle        groups;    -   (d) to provide a back strengthening machine whose advantages        also include the strengthening of intervertebral muscles;    -   (e) to provide a back strengthening machine which allows a user        to perform the exercise in a standing then squatting up and down        repeated motion position;    -   (f) to provide a back strengthening machine whose muscle        strengthening technique will help decrease vertebrae        subluxations within the spinal column;    -   (g) to provide a back strengthening machine whose muscle        strengthening technique will help to cease the onset of back        pain symptoms;    -   (h) to provide a back strengthening machine, which will decrease        the malfunctions of the spine, that cause nerves to become        pinched between vertebrae.    -   (i) to provide a back strengthening machine, which will        stimulate the piezoelectric effect within the spinal column and        all back structures.

SUMMARY

In accordance with the present invention an improved back strengtheningmachine comprises a rolling cushion assembly unit with a convex shapedcenter adhered to a weight resistance assembly unit, base assembly unit,and a handle bar assembly unit.

DETAILED DESCRIPTION—FIG. 1-7—PREFERRED EMBODIMENT

A preferred embodiment of the back strengthening machine of the presentinvention is illustrated in FIG. 1 (left side perspective view). Twometal vertical bars adhered to weight resistance assembly unit 2(FIG. 1) insert into hollowed cubes adhered to rolling cushion assemblyunit 1 (FIG. 1). The bottom vertical bar adhered to weight resistanceassembly unit 2 (FIG. 1) inserts into top bar adhered to base assemblyunit 3 (FIG. 1). The base bar adhered to handlebar assembly unit 4(FIG. 1) inserts into larger base bar adhered to base assembly unit 3(FIG. 1). Top bar adhered to handlebar assembly unit 4 (FIG. 1) insertsinto larger bottom bar adhered to handlebar assembly unit 4 (FIG. 1).

Operation—FIG. 1

The manner of using the improved back strengthening machine tostrengthen all dorsal muscle groups is not identical to that for backstrengthening machines in present use. In operation a user will stand ontop of base of base assembly unit 3, hold onto hand grips adhered tohandlebar assembly unit 4, and then press onto the rolling cushionadhered to rolling cushion assembly unit 1, while aligning the elevatedconvex shape onto the spinal location. Next, the user will use kneeflexion to maintain the spinning cushion adhered to rolling cushionassembly unit 1 to spin freely up and down the user's back structures.

During operation of the back strengthening machine a user will benefitfrom the strengthening of all dorsal muscle groups, thereby increasingthe stability of all back structures.

I claim:
 1. A back strengthening machine having a rolling cushion with aconvex shaped middle section attached to a weight resistance unit. 2.The back strengthening machine of claim 1 having a said rolling cushionwith an innovative contour that also strengthens intervertebral muscles,thereby increasing the overall stability of all back structures.
 3. Theback strengthening machine of claim 1 is operated by a user during whichsaid user will perform repetitious knee flexion to maintain spinningcushion adhered to the rolling cushion assembly unit to spin freely upand the user's back and spinal structures.
 4. The back strengtheningmachine of claim 2 wherein during said operation said user activates thesaid rolling cushion with said rolling cushion assembly unit to activateweight resistance unit to freely roll up and down the back.
 5. The backstrengthening machine of claim 3 wherein during said operation the saiduser will activate the said back strengthening machine to apply an evenamount of weight resistance to all back surfaces.
 6. The backstrengthening machine of claim 4 wherein during said operation the saiduser remains in a prone position on the bed cushion.
 7. The backstrengthening machine of claim 4 wherein during said operation the saidweight resistance applied to said all back surfaces will strengthen alldorsal muscle groups and activate the piezoelectric effect to all backstructures.
